The correct answer is Only (A) and (C) are true
Explanation:
In a study or research, the control group is the one that does not receive a treatment. This means, in this case, the control group includes those who only drink the green tea without the herbs because they serve as a standard to measure the effects of the herbs. This makes statement A (The "only green tea" group serves as the control group) true; also, the group receiving the herbs is the experimental group.
On the other hand, a double-blind study is one in which the researchers and the participants ignore who is receiving the treatment, which guarantees there is objectivity. This occurs in the study presented because neither the researcher nor the subjects known who received the herbal mix. Thus, statement C (This study is double-blind) is true.
Finally, a study is classified as observational if there is not intervention but the researchers just observe participants to study a phenomenon. This does not occur in the study presented because there is an intervention through the herbal treatment, and therefore the study is not observational.
